A device for drainage of a pulp web, particularly a tissue web, having a first pressing zone having a first pressing zone length through which the pulp web is fed horizontally between a circulating, permeable band and a circulating, permeable support band. The first pressing zone is designed such that a fluid can flow through the band, the pulp web and the support band at least on one part of the first pressing zone length. In addition, the device has a subsequent second pressing zone having a second pressing zone length. The pulp web is guided through the second pressing zone between two bands having differing compressibility.

A wiper blade is proposed, which is for cleaning for windows, particularly of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14), which can be placed against the window (22) and is connected to an elongated, spring-elastic support element (12) so that their longitudinal axes are parallel, which support element (12) is directly connected to a device (16) for connecting the wiper blade to a driven wiper arm (18). The support element (12) has two band-like spring strips (28, 30), which are situated in a plane that is disposed in front of the window, essentially parallel to the window, and whose one, lower band surfaces (13) are oriented toward the window and whose adjacent, inner longitudinal edges (48), which are disposed spaced a distance (34) apart from each other, each protrude into a respective longitudinal groove (54, 56, or 106), which grooves are associated with each longitudinal edge and are open toward a respective longitudinal side of the wiper strip (14), and these two spring strips (36, 38) are connected to each other by at least two crosspieces (36, 38) disposed spaced apart from each other in the longitudinal direction. Manufacturing advantages for the wiper blade according to the invention are achieved if each crosspiece (36, 38) has a middle section (42) which extends spaced a distance (44) apart from the upper band surfaces (11) of the spring strips (28, 30), producing bridge-like crosspieces, where the distance (34) between the two longitudinal strips (28, 30) is less than the bridge width (46).

The present invention refers generally to a new family of antenna arrays that are able to operate simultaneously at two different frequency bands, while featuring dual-polarization at both bands. The design is suitable for applications where the two bands are centered at two frequencies f1 and f2 such that the ratio between the larger frequency (f2) to the smaller frequency (f1) is f2 / f1<1.5. The dual-band dual-polarization feature is achieved mainly by means of the physical position of the antenna elements within the array. Also, some particular antenna elements are newly disclosed to enhance the antenna performance.

The antenna of said transmitter is a microstrip antenna. A rear edge of its patch is provided with a short circuit by means of which a quarter-wave primary resonance can be excited by a coplanar line formed by two coupling slots in an area. Separator slots separate said area from another area in which a secondary resonance can be established at twice the frequency of the primary resonance from a slotted line extending one slot of the coplanar line. The invention applies in particular to the production of a dual-mode mobile telephone to the GSM and DCS standards.

Eyewear, such as goggles, includes a frame, a lens supported by the frame, and an outrigger that is pivotally mounted to sides of the frame. An elastic band is mounted to the outrigger. The elastic band is made from two band arms that are connected on one end to form a loop, and at the opposite end, the arms have loose ends, but can be attached and detached from the outrigger. The attachable and detachable aspect of the band provides the opportunity to interchange the band when the band is worn or broken, or alternatively, a completely different style of band can be used with the eyewear. For example, a traditional looking band having a stretchable elastic textile band can be substituted for the band with two arms.

The invention relates to a wireless instrument (1) including a wristband (2) having two band portions (2a, 2b) connected to opposite edges of a casing (3), each band portion having upper and lower surfaces (21,22). At least one single loop antenna (4a) is embedded in one band portion and extends between the corresponding upper and lower surfaces. This single loop antenna is connected via feeding lines (7) through one edge of the casing to an antenna receiver (5). The loop antenna and the feeding lines define a radiating element, wherein the feeding lines are arranged so as to be a negligible part of this antenna radiating element.
